I read a lot of pages, but contribute very little. On top of that, about the only edits I tend to do are getting rid of vandalism.
Interest: 3D computer graphics and animation (I use Blender 3D for making the stuff, then use YafRay and Indigo Renderer to render what I make). Networking, electronic entertainment (video games), basically anything that's electronic or has a computer chip in it..
Sound synthesis is another topic I find great interest in. CS-80 and the Synclavier are probably some of my favorites.
